Six polyvinyl chloride and six polyethylene angioplasty balloons were inflated six times each under laboratory conditions. Outside diameter of the balloons was measured on initial and final inflations; volume was measured by water displacement at each inflation. In addition, three balloons in either group were constricted with a silk suture around the midportion. Balloons were then intentionally ruptured and the rupture site recorded. The diameters of the polyvinyl chloride balloons increased over six inflations, while they remained relatively constant for the polyethylene balloons. Rupture sites were in the area of the balloon that had the greatest outside diameter, and the tears were longitudinal.
在实验室条件下,对六个聚氯乙烯血管成形术球囊和六个聚乙烯血管成形术球囊分别进行六次充气。在初次充气和末次充气时测量球囊的外径;每次充气时通过排水法测量体积。此外,每组中的三个球囊在中部用丝线结扎使其收缩。然后故意使球囊破裂并记录破裂部位。聚氯乙烯球囊的直径在六次充气过程中增大,而聚乙烯球囊的直径则保持相对恒定。破裂部位在球囊外径最大的区域,且撕裂为纵向。
